To all it may concern, "'Beiit' 'known that I, HoPPiNG MURRELL, av

citizen ofthe United States of America, and

ening all the wires at one operation, means being not only provided for independently tilghtening the wires, but also for tightening a the Wires simultaneouslyfas more fully hereinafter set forth.

To the accomplishment of this object and.

. such others as may hereinafter appear the invention consists of the arts and combination of parts hereinafter ully described, and particularly pointed out in the appended claims, reference being had to the-accompanying drawings, forming a part of this specification, in which the same reference characters designate like parts throughout the several views.

In the drawings, A designates a stretcher bar or post carrying a laterally-projecting ri id block a about midway its ends. T on h a horizontal hole in this block a screw loosely passes, the outer end of this screw being provided with ahandle C, whereby the screw may be turned. This handle may slide in the head. of the screw, if desired, in order that the'leverage may be increased.

A series of independent stretchers are attached to the bar A, each stretcher consisting desirably of a threaded rod .76, passed through the stretcher-bar, a turnbuckle, K, screwed on the forward end thereof, another threaded rod 7c, screwed into the turnbuckle and'having a loose ring at its forward end, which connects it with a wire-clamp L of any suitable type.

The screw is a double screw having half its threads ri ht and the other half left, the two kinds of t reads meeting about midway of the len th of the screw, thereby forming substantia ly two screws 1) and b The nut E is Inounted on one of the-screws, and a similar Specification of Tietters Patent. Application 'fiieiiiiar n' 28, lacs." seria mi 308.569.

.nut H is mounted onthe other screw. 'The Efnu't H is provided with oppositely-extending ears h, to which are permanentlyconnecte'd the inner ends of chains G the outeraorfree Patented. July @1, 1906'. V i

ends of these chains G being-'adapted to 'be linked into 1 open hoo'ks 07'; attached to: the

stfetcherfbar near the ends: thereof The nut E 'is also 'provided with oppositely-em "tendingears'e, and to these ears are-connect ed the reipec'tive inner ends of another; pair of chains hooks':a From-these eyes the chainsmextend forwardly, andtheir forward ends are detachably linked over open hooks f, proj ecting rearwardly from acollar F, mounted loosely upon the screw near the'head thereof,

this collar being prevented from sliding forwardly on the screw by means of a suitable stop or flange on the screw.

In using this apparatus the forwardendof the screw is put against one of the fence-posts and the rear end of the screw is supported on a suitable frame supported on the ground. In the present instance I have shown this ywhich chains are'carried'forward' and= passed through eyes a carried by the stret'cher bar' ati pointsnear the' respecti've support to consist of a post J and one or more braces 1'; but it is obviousthat any suitable support may be employed.f The stretcher bar A is then raised to an upright position, and the Wire-clamps L are connected to' the respective longitudinal. wires of the fence.

Then either the, chain G or the chain D is drawn taut and enga ed with its hooks, the

In the drawings the chain D is shown-taut. Then when the screw is rotated to the right the nut E will be drawn rearward, thus pull ing the stretcher-bar rearward and ti hten ing all the wires." At the same time t e nut H-will travel forwardly, thus slacking its chain. Then if further stretching is desired the chains G are ti htened (by detaching their free ends from t e hooks a and engaging. links of the chains nearer the nut H) and the screw is rotated in the opposite direction, r

D. This alternative operation is repeated.

until the wires are drawn suiliciently taut. It \will be observed-that by this arrangement the slack of a great length of fencing'may be taken up and the wires held until they are stapled to the post. Should any of the wires 9 other chain being al owed to remain loose.

have more slackness than the others, it is obvious that they may be individually tightened by means of the turnbuckle connectlons dependently-operable wire tighteners connected thereto each being provided with means for engagement with one of the Wires of the fence, a screw adapted to engage a fenceost at one end, means for su porting the ot er end of the screw, a pair 0 nuts on the screw adapted to travel simultaneously in opposite directions thereon-when the screw is turned, and chain connections between each nut and the stretcher-bar, for the purposes set forth.

2. In combination with a stretcher-bar carrying means for engagement with the longitudinal wires of the fence, of a screw and means for supporting it, a air of nuts adapted to simultaneously trave in opposite directions on the screw when the screw is turned, a pair of chains connecting each nut to the stretcher-bar near the outer ends thereof, substantially as set forth.

In testimony whereof I hereunto aflix my signature, in the resence of two witnesses, this 24th day of March, 1906.

HOPPING MU RRELL.
